There are different opportunities to contact me.
The easiest way: You can visit me at my house to set the timetable up. (Translation of the adress: From the supermarket La Union 3 blocks to the east and 30 Yards to the north, on the left hand side - Original in spanish: Supermercado La Union 3 cuadras arriba 30 varas al norte, mano izqierda)
When you already do speak a few words of spanish you can call me, too: 05088274626
You can send me an email (I do understand english, too):
When you already stay in León and want to find my house, this map will help you. On the upper right there's a foto of my house. Knock the door on the left hand side at any day or hour.
